The fleets of Chaos are primarily made of ships that have turned traitor over the millennia. As such, a Chaos fleet can appear like a damned parody of the Imperial Navy's history, full of ships that have long since left service and are now rarely seen outside of the service of the Dark Gods.[1][2][3] Chaos fleets often operate older vessels from a more enlightened time, resulting in their ships being of superior designs to their contemporary Imperial counterparts.[7]

There are exceptions to this, of course. From the lowly Idolator Raider to the fearsome Planet Killer, Chaos has been known to make ships of its own, much to the detriment of Emperor's forces.[1][2]
